Abstract

The morphology of chloride cells in the gill of the skate Torpedo marmorata is described from a light and an electron microscopic study. Chloride cells have been regularly observed in both the gill filament (or primary epithelium) and the lamellae (or secondary epithelium). Chloride cells located in the filament usually display convex apical regions with microvilli protruding amongst microridges of neighbouring pavement cells, whereas chloride cells in the lamellae are located between the two epithelial layers, and contact with the external milieu is via a narrow apical opening. Present observations are discussed in relation to data on the presence of chloride cells in the lamellae of marine teleost fish, and it is suggested that the occurrence of chloride cells all along the lamellae might be in some way inversely related to fish activity.
